Thermal Cycler

SF-96 thermal cycler covers the basic requirements to meet daily experiments with stable performance and competitive price. By using the latest solid-state Peltier technology combining advanced elasticity heated lid technology, our thermal cycler can provide you a highly-precision of temperature settings, great block uniformity and a fast temperature adjustment.

• Faster Heating

SF-96 is currently one of the best cost-effective thermal cyclers on the market. With the latest semiconductor temperature control modules, it can ensure you the correct and accurate temperature by great block uniformity and a remarkable fast temperature adjustment. SF-96 provides you a 96-position sample block with 0.2ml sample tubes. It has cylindered set design to effectively increase the speed of temperature adjustment.

• Heated lid

The heated lid has a flush fitting enclosure to ensure a complete seal, eliminating airflow across the surface of the sample block. This means that the temperature control is maintained regardless of environmental conditions. The in-lid surface is spring-mounted to ensure even contact and pressure on all lids regardless of the tube height, ensuring no condensation of water vapor on the tube lids. A specially designed, microprocessor controlled heating element, compensates the temperature fluctuations of the lid.

Double temperature control

- Sample block temperature control
Temperature control module can monitor the real-time temperature of the sample block and display the result on the screen. This mode applies to maintain a longer time PCR reaction to every step.

- Simulation sample tube temperature control
SF-96 applies an advanced software algorithms to control the temperature of the simulation sample tubes. The software can calculate the temperature of samples continually and adjust the temperature of the block to meet a consistency of the sample and the block.


Polymerase chain reaction (PCR) is a technique widely used in Molecular biology. As PCR progresses, the DNA thus generated itself used as a template for replication. With PCR it is possible to amplify a single or few copies of a specific DNA fragment across several orders of magnitude, generating millions or more copies of the DNA fragments. PCR is now a common and often-indispensable technique used in medical and biological research for a variety of applications.

Gel electrophoresis has been widely used to do the separation for the PCR products. Electrophoresis refers to the Electromotive force (EMF) that is used to move the molecules through the gel matrix. By placing the molecules in wells in the gel and applying an electric current, the molecules will move through the matrix at different rates, usually determined by mass, toward the positive Anode if negatively charged or toward the negative Cathode if positively charged.

Gel Documentation System can analyze and preserve the result of gel electrophoresis. It can be used to determine whether a PCR experiment is succeed or not by observing the gel imaging which has been excited by the UV lamp in a Gel Documentation System. According to the image we can carry out the progress of the DNA analysis and research. A visible and clear band means a specific DNA fragment that has been amplified specifically and effectively.
